Biggest Blunder?

[ggodw000]

when i graduated my college in '06 i attempted several times during last 10 years to jump start my OS project. The startup code was supplied in 4xx level course. Biggest blunder was forgetting where i left off and starting a new. It was costly. This time, starting beginning of 2016, I setup git repo and continue as long as it takes, however long the interruption be, i swore to start where i left off previously.

Hi,


Just now something else happened. While I mapped the whole data used by the kernel and marked as free the rest of physical memory, I...

...forgot to map the framebuffer.

Wondering the whole afternoon why did it triple fault.

I've been in #osdev at that time

I've been in village without Internet, and my hard drive fully crashed with all data on it. In Git there's been old version, so development is freezed for 3 months.

I push to my repository every time I make a change, and you should too. My most recent push is from 3 days, and since then all I have done is changed a debug message from "ACPI APIC" to "ACPI MADT" so I know I'm never losing anything.

without Internet

Clone a bare git repo to USB stick and push/pull there as long as there is no internet.
USB repos are also good for small personal stuff you don't want to put to Internet (notes, etc).

OK, I'll do it next summer. But in summer of 2015 I don't known about it.

I posted (read: bragged) about my operating system on a Q/A website and it received about 150,000 views. I could've provided a GitHub link there but I instead asked people to email or message me individually and I'd send them the link. Guess what, I lost a great promotional opportunity for my OS. I'm not sure whether I'll have the same opportunity, again.

My biggest blunder was probably getting interested in the subject in the first place.

My biggest blunder was forgetting to clear the BSS, thinking that if I declared global variables as 0, that wouldn't matter. Turns out it did, and I ended up with a frustrating Heisenbug for 5 months.

Overthinking.

I do it quite often...
